Abstract

The utility model discloses a tensile type flat power cable with an elastic anti-extrusion structure. The tensile type flat power cable comprises three conductors which are parallelly placed at intervals; the exterior of each conductor is wrapped with an ethylene-propylene-diene mischpolymere rubber insulation layer, such that an insulated wire core can be formed; the exterior of the insulated wire core is coated with an anti-extrusion layer which is formed through the extrusion molding of an elastic material; a plurality of through holes are circumferentially arranged in each anti-extrusion layer; the exterior of each anti-extrusion layer is provided with a shielding layer; a plurality of elastic steel wires are circumferentially arranged in each shielding layer; the exterior of each shielding layer is provided with a protective layer; the three insulated wire cores coated with the protective layers form a cable core; and a flat ethylene-propylene-diene mischpolymere rubber sheath layer is extruded and molded on the exterior of the cable core. According to the tensile type flat power cable of the utility model which is of a reasonable structure, the ethylene-propylene-diene mischpolymere rubber insulation layers and the ethylene-propylene-diene mischpolymere rubber sheath layer are adopted, and at the same time, the anti-extrusion layers are also adopted in a matched manner, and therefore, the anti-extrusion performance of the cable when the cable is mounted in moving, corrosion-prevention and narrow spaces can be improved; and further, the cable has excellent tensile strength, and the cable core can be excellently protected, and the service life of the cable can be prolonged.

Description

A kind of tensile type flat power cable with elastic reactance extrusion structure

technical field:

The utility model relates to power cable, relates in particular to a kind of tensile type flat power cable with elastic reactance extrusion structure.

background technology:

Relatively round cable, flat cable more has the advantages such as the installing space of saving and cost, and in the situation that heart yearn radical is identical, its bending radius is less than round cable.

In industries such as metallurgy, electric power, petrochemical industry, have in the mobile specific (special) requirements occasion such as anticorrosion, cable laying is more prone to be subject to extraneous extruding and stretching after installing, thereby occurs the problems such as stress deformation.

utility model content:

In order to make up prior art problem, the purpose of this utility model is to provide a kind of tensile type flat power cable with elastic reactance extrusion structure, and structural design is compact, has improved the anti-extrusion performance of cable in actual application environment.

The technical solution of the utility model is as follows:

Tensile type flat power cable with elastic reactance extrusion structure, comprise three conductors parallel and place at interval, it is characterized in that: described conductor is coated with ethylene propylene diene rubber insulating barrier and forms insulated wire cores, insulated wire cores is coated with the anti-extrusion layer of elastomeric material extrusion moulding, in anti-extrusion layer, along annular spread, there are several through holes, anti-extrusion layer is provided with screen outward, screen has some elastic wires along annular spread, screen peripheral hardware matcoveredn, three insulated wire cores of coated protective layer form cable core, the outer extrusion moulding of cable core has the ethylene propylene diene rubber restrictive coating of flat.

The described tensile type flat power cable with elastic reactance extrusion structure, is characterized in that: described screen adopts the overlapping wrapped formation of aluminium-plastic tape, and the wrapped rate of putting up is not less than 48%, and some elastic wires are between the wrapped aluminium-plastic tape of putting up.

The utility model has the advantages that:

The utility model structure is established rationally; by adopting ethylene propylene diene rubber insulating barrier and restrictive coating; coordinate the design of anti-extrusion layer simultaneously; improved the anti-extrusion performance of cable laying installation in mobile anticorrosion and small space; in addition; cable also has good tensile property, can be good at protecting cable core, has extended useful life.

accompanying drawing explanation:

Fig. 1 is structural representation of the present utility model.

embodiment:

Referring to Fig. 1:

Tensile type flat power cable with elastic reactance extrusion structure, comprise three conductors 1 parallel and place at interval, conductor 1 is coated with ethylene propylene diene rubber insulating barrier 2 and forms insulated wire cores, insulated wire cores is coated with the anti-extrusion layer 3 of elastomeric material extrusion moulding, in anti-extrusion layer 3, along annular spread, there are several through holes 4, the outer screen 5 that is provided with of anti-extrusion layer 3, screen 5 has some elastic wires 6 along annular spread, screen 5 peripheral hardware matcoveredns 7, three insulated wire cores of coated protective layer 7 form cable core, the outer extrusion moulding of cable core has the ethylene propylene diene rubber restrictive coating 8 of flat.

Screen 5 adopts the overlapping wrapped formation of aluminium-plastic tape, and the wrapped rate of putting up is not less than 48%, and some elastic wires 6 are between the wrapped aluminium-plastic tape of putting up.
